OBJECTIVE Currently, diagnosis of cracked teeth generally depends upon the overall clinical assessment, or on exclusion of other clinical possibilities, not primarily on the direct identification of cracks themselves. Owing to its short wavelength in hard tissues and associated high resolution, ultrasound has the potential to allow detection of cracks(More)
We have measured the low-frequency ("unclamped") electrooptic and piezoelectric coefficients in undoped BaTiO, and SrSa, -Nh2O6 (x = 0.61) crystals using interferometric techniques. The Contribution of the piezoelectric effect to the Pockels measurements is discussed. For an applied ac electric field in the range 0.1-200 V/cm, the electrooptic and(More)
